Business Strategy and the Environment, EarlyView.ABSTRACT Industrial symbiosis (IS) represents a key strategy for industrial decarbonisation (ID) by converting one industry's waste into valuable inputs for another, reducing emissions and resource extraction. Scientific studies have explored the concept, implementation approaches and theoretical foundations of IS.

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Journal of Rock Mechanics and Geotechnical EngineeringThe Rock-soil interface is a common geological interface. Due to mechanical differences between soil and rock, the stress waves generated by underground blasting undergo intense polarization when crossing the rock-soil interface, making propagation laws ...

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.
